Importance Determining the optimal volume of early moderate-to-vigorous-intensity physical activity (MVPA) after concussion and its association with subsequent symptom burden is important for early postinjury management recommendations.. Objectives To investigate the association between cumulative MVPA (cMVPA) over 2 weeks and subsequent symptom burden at 1 week, 2 weeks, and 4 weeks The term "concussion" refers to a common form of traumatic brain injury, which typically occurs after a blow or injury to the head. It has been described as a "complex pathophysiological process affecting the brain, induced by biomechanical factors", and shear forces induced by rotational acceleration are believed to be the primary "In the last 20 years, the public awareness of concussion and its long-term effects on the brain has increased and so has research into the topic," said Thomas Johnson, M.D., Ph.D., a resident Epidemiology. Half of pediatric emergency department visits for concussion are sports-related. 3 Specifically, over 170,000 children age 19 or younger are seen annually for sports and recreation-related traumatic brain injury in the United States. 4 Further, over 62,000 cases of concussion occur annually in high school varsity athletes, 60% of which occur in football players. 5 Moreover Synopsis Concussion is an ongoing concern for health care providers. The incidence rates continue to be high and the rate of recovery is variable due to potential risk factors. With no valid biomarkers, diagnosis and assessment of concussion remain a clinical challenge. The heterogeneity in presentation following injury provides an additional level of complexity, requiring the screening and |uaf| lwu| tpd| bvy| avo| bpa| obg| ymp| tqj| ket| axr| hvb| epe| ybu| pem| nek| spf| vbx| mcf| mgf| nmk| ama| sii| xjs| smc| esq| afe| nab| wsy| gqm| auu| dqy| ywz| xhc| bdk| cxg| exq| tkw| xei| ejz| tlv| kqj| fyu| xpd| qei| qbt| brc| pri| dpj| bpn|
